- Working out problems is the only way to learn mathematics.
- By doing the problems you can gauge how well you understand the course material.
- The homework problems are representative of the types of problems that will appear on the examinations.

Math 128 is a continuation of MATH 127 (Calculus for Life and Social
Sciences I). This course covers elementary techniques of integration,
introduction to differential equations, applications to several mathematical
models in the life and social sciences, and multivariate
functions and partial derivatives.

Applied Calculus, 4th edition (Hughes-Hallet), available as an ebook
with your WileyPLUS account. If interested, you should be able to find
a used copy of the physical book online.
